One evening a church was having a new members class. There were three couples wishing to join the church. After the class was nearly done, the minister told them "Now one last thing as part of joining our church is you must refrain from sex for three weeks."

The couples returned three weeks later to complete their class. The minister asked the couples if they were able to refrain from sex for three weeks.

The first was an old couple in their 70'*. The husband replied, "Oh it was no trouble at all not having sex."

The minister asked the second couple, who were in their 40'*. The husband replied "Well the first week was fine. But the second week was getting tough. Finally the third week I had to sleep on the couch to make it through."

Finally the minister looked at the third couple, who had only been married for a few weeks. The husband again responded "Man was that hard! I barely made it through the first two days. Then on the third day, I saw her bend over to pick up a can of corn and I couldn't stand it, so I took her right there."

The minister shook his head. "You realize you are not welcome in our church now?"

The husband said "Yeah, we're not welcome at the supermarket now either."
